Forty years ago today, August 30, 1965, Bob Dylan released the album Highway 61 Revisited. It went on to peak at number 3 on the Billboard album charts, but it will finish fourth on Rolling Stone’s list of the top albums of all time. From Ballad of a Thin Man:

You've been with the professorsAnd they've all liked your looksWith great lawyers you haveDiscussed lepers and crooksYou've been through all ofF. Scott Fitzgerald's booksYou're very well readIt's well known

Because something is happening hereBut you don't know what it isDo you, Mister Jones?
